The PLC4510 from Laird is a heavy duty, all-welded, directional Yagi antenna capable of handling up to 250 watts of input power. All of the PLC Yagis, have their elements fully welded to the boom. These welds are on the inside of the boom to eliminate noise and enhance electrical performance. Complete weatherability is ensured by enclosing the feed system in a potted PVC radome that will stand up to your most demanding requirements. The pigtail feed will withstand a 50 pound pull, and makes connector weatherproofing simple. There are no moveable components, so you never have to worry about adjustments or loose parts. All hardware is stainless steel for long life.
